what is one easy addition equation?
1 + 1 = 2
how did you get this ?
you add 1 and 1 together and you will get your solution.
Answer:
Step-by-step explanation:
Let x be the random variable representing the the length of newborn babies (in inches). Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
From the information given,
µ = 20 inches
σ = 2.6 inches
the probability that a given infant is between 14.8 and 25.2 inches long is expressed as
P(14.8 ≤ x ≤ 25.2)
For x = 14.8,
z = (14.8 - 20)/2.6 = - 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.023
For x = 25.2
z = (25.2 - 20)/2.6 = 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.98
Therefore,
P(14.8 ≤ x ≤ 25.2) = 0.98 - 0.23 = 0.75
50 x 50 + 100 - 43 = 2557
Answer:
E(3.75,-2.5)
G(-0.75,-3)
Step-by-step explanation:
Point E is the midpoint of the segment AB, then it has coordinates
Point F is the midpoint of the segment EB, then it has coordinates
Let S be the midpoint of segment CB, then it has coordinates
Point G is the midpoint of segment CS, then its coordinates are
